RAZOR-STROPPER.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed December 10, 1912. Serial No. 736,022.

To all whom it may concern Be it known that I, ELISHA W. COLE,'a citizen of the United States, residing at Charlotte, in the county of Mecklenburg and State of North Carolina, have invented a new and useful Razor-Stropper, of which the following is a specification.

One object of the present invention is to provide a razor blade stropper in which the blade holder is tilted directly by lateral pressure caused by the strop, the use of intermediate gearing being thereby avoided.

It is within the scope of the invention to improve generally, and to enhance the utility of, devices of that type to which the present invention appertains.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of What is claimed, without departing from the spirit of the invention.

In the drawing: Figure 1 shows the invention in longitudinal section; Fig. 2 is a front elevation; Fig. 3 is an end elevation; Fig. 4 is an elevation showing the opposite end of the structure from that depicted in Fig. 3; Fig. 5 is a side elevation of the blade clamp.

In carrying out the invention there is provided a support, denoted generally by the numeral 1, the support 1 comprising side plates 2 and 3. A loop-shaped handle 4 is provided, the same being oflset as shown at 5, the extremities of the handle 1 terminating in laterally extended fingers 6 which are pivotally supported in the side plates 2 and 3.

The extremities of a pair of rear shafts 7 are fixedly mounted in the side plate 2. The ends of intermediate shafts 8 and 9 are similarly mounted in the side plate 2, meaning thereby that the shafts 7 at one end, are rigidly connected to the side plate 2, a single forward shaft 10 being fixedly mounted at one end in the side plate 2. The shafts 7, 8 and 9 upon each side of the structure are in substantial alinement, the shaft 10 being located between the shafts 7, 8 and 9. Into the ends of the shafts 7, 8 and 10 are inserted screws 11, the screws engaging the side plate 3. The shafts 7, 8 and 10 constitute means for holding the side plates together, the ends of the shafts 9 preferably, merely extending through openings in the side plate 3. Rollers 12 are mounted on the shafts 7, between the side plates 3, the shafts 8 carrying rollers 14, the shafts 9 carrying rollers 15, and the shaft 10 carrying a roller 16.

In claiming the invention, I shall refer to spaced pairs of guides, meaning thereby, as representing one pair, the rollers 14, and as representing the other pair, the rollers 12.

The side plate 3 is provided with a keyhole slot 17 including an extension 18, the body portion of the keyhole slot 17 being located between the shafts 7 and 8, and the extension 18 of the keyhole slot being prolonged between the shafts 8 and 9.

Terminally mounted in the rear ends of the plates 2 and 3 is a pin 19, adapted to be mounted in any one pair of openings 26 which are formed in the arms 20 of a movable, blade holding frame. The arms 20 are connected by a socket 21, the edges of which are prolonged to form jaws 22. Extensions 23 protrude in opposite directions from the ends of the socket 21, the extensions 23 supporting shafts 2 1 carrying rollers or guides 25. The rollers 25 are located between the rollers or guides 14 and 12. A blade clamp 27 is provided and is adapted to receive a blade 37.

The blade clamp and the blade, positioned as shown in Fig. 5, are thrust endwise through the keyhole slot 17 in the plate 3 of the support 1, into the blade holding frame. A flexible strop 38 is looped around the roller 10, the ends of the strop being thence passed between the two sets of rollers 8 and 9, and the rollers 25 of the blade holding frame being located between the constituent portions of the strop. The ends of the strop are then passed between the rollers 12, the parts being positioned as shown in Fig. 1. Suppose, referring to Fig. 1, that one end of the strop 38 has been drawn to the limit of its movement in the direction of the arrow A, the blade 37 having been swung into contact with the other end of the strop 38. Suppose that the said other end of the strop is drawn in the direction of the arrow B. Then, the bulged portion of the strop 38, 1ying between the rollers 8 and 7 on the right hand side of Fig. 1, will be straightened out, and the blade holding frame and the blade 11, will be straightened out, before longitudinal movement is imparted to that portion of the strep 38 which lies between the roller 14 and the roller 12 upon the left hand side of Fig. 1. Consequently, the blade 37 will be swung away from one portion of the strep, before the other portion of the strep is moved longitudinally to effect a sharpening of the blade. Any engagement of the cutting edge'of the blade in the strep 38, will, therefore, be avoided.

It is to be observed that due to the construction above pointed out, any intermediate gearing for swinging the blade holding frame is rendered unnecessary, the mere straightening out of the bulged portion of the strep serving to effect the necessary tilting of the frame.

The rollers 14 and 12 constitute primary guides for directing the longitudinal movement. of the strep 38 and the rollers 25 constitute secondary guides, which being engaged by the bulged portions of the strep 38, constitute the sole means for imparting movement to the blade holding frame.

Having thus described the invention,what is claimed is A razor blade stropper embodying a support; a strep receiving element at one end thereof; spaced pairs of guides on the support; a blade holder; means for pivoting the blade holder by one end at the other end of the support, the holder projecting into the space between the pairs of guides; a strep looped over the strep receiving element and engaged with the inner portions of the guides and opposed guides on the holder located in the space between the pairs of guides on the support and projecting laterally beyond said guides, the outer portions of the guides on the holder engaging the strep, thereby to form two oppositely bulged portions in the strep, between the pairs of guides on the holder, whereby when the respective ends of the strep are drawn upon, the holder will be swung in opposite directions, by the cooperation between the bulged portions of the strep and the guides on the holder.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
